Retool Database connection limits?

I see that the Retool Database docs have information about the storage size limits of Retool Database, but what I'm not seeing is any information about bandwidth or number of concurrent connections. Is this known/available anywhere else? Thanks!

meant to say "information about limits to bandwidth or number of concurrent connections"...

Basically I'm evaluating whether to use Retool Database or some other hosted Postgres instance (e.g. Supabase) for a new project, knowing that I will want to allow access to that database from other apps at some point.
